Step 3: Search the Package
You can search for Java 17 package to check if it is available in the Debian repo by running apt-cache search openjdk | grep 17 command as shown below.
root@debian:~# apt-cache search openjdk | grep 17
openjdk-17-dbg - Java runtime based on OpenJDK (debugging symbols)

Step 4: Install Java 17
There are multiple ways to install Java in which we will see the most preferred way of installation. Basically it is preferred to install either from Debian Repo or using standalone Debian package. We will see both the ways.
a) From Debian Repo
This is probably one of the most preferred method to install not only the Java package but all other packages as well which are available from Debian repo. You can just use apt package manager to download and install the specific Java version using below command.
root@debian:~# apt install openjdk-17-jdk openjdk-17-jre

b) Using DEB Package
This is another method where you need to go to Oracle official website and download Java 17 using wget utility as shown below. This will download the deb package in local system directory.
root@debian:~# wget https://download.oracle.com/java/17/latest/jdk-17_linux-x64_bin.deb --2022-04-13 03:37:28-- https://download.oracle.com/java/17/latest/jdk-17_linux-x64_bin.deb Resolving download.oracle.com (download.oracle.com)... 49.44.204.29 Connecting to download.oracle.com (download.oracle.com)|49.44.204.29|:443... connected.

Then install Java 17 package by using apt install ./jdk-17_linux-x64_bin.deb command as shown below.
root@debian:~# apt install ./jdk-17_linux-x64_bin.deb Reading package lists... Done Building dependency tree... Done Reading state information... Done Note, selecting 'jdk-17' instead of './jdk-17_linux-x64_bin.deb' The following NEW packages will be installed: jdk-17 0 upgraded, 1 newly installed, 0 to remove and 196 not upgraded. After this operation, 317 MB of additional disk space will be used. Get:1 /root/jdk-17_linux-x64_bin.deb jdk-17 amd64 17.0.2-ga [155 MB] Selecting previously unselected package jdk-17.

Step 5: Check Version
After successful installation, you can check the java version by using java --version command as shown below.
root@debian:~# java --version openjdk 17.0.2 2022-01-18 OpenJDK Runtime Environment (build 17.0.2+8-Debian-1deb11u1) OpenJDK 64-Bit Server VM (build 17.0.2+8-Debian-1deb11u1, mixed mode, sharing)
Step 6: Configure Java(Optional)
In case if you see Java path are not set then you can set it using below export command. But please keep in mind that this is just the temporary way to set the JAVA_HOME and PATH variables. If you want to make it permanent then put this entry in ~/.bash_profile or ~/.bashrc.
root@debian:~# export JAVA_HOME=/opt/jdk17 root@debian:~# export PATH=$PATH:$JAVA_HOME/bin
Step 7: Uninstall Java 17
If you ever decide to uninstall Java 17 package from the system then depending on the method you chose to install, you have to follow the below uninstallation method.
a) When installed from Debian Repo
If you installed the package from Debian repo then use below apt remove command to uninstall Java 17 from your System.
root@debian:~# apt remove openjdk-17-jdk openjdk-17-jre Reading package lists... Done Building dependency tree... Done Reading state information...
